CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority from Chinese Patent Application No. 202321871155.3, filed on Jul. 14, 2023. The content of the aforementioned application, including any intervening amendments made thereto, is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This application relates to heat dissipation, more particular to a water-cooling radiator with staggered-overlap heat-dissipation fins.

BACKGROUND

Radiator is designed for cooling and protecting electronic devices. Enhanced performance of computers and other electronic devices result in increasingly-growing power consumption.

In the prior art, water-cooling radiators have excellent heat-dissipation effects. However, to further improve the cooling efficiency of the existing water-cooling radiators, it is only possible to introduce a fan, increase the planar area or add heat pipes, which will increase its volume. Besides, a larger water-cooling radiator may be not compatible with the increasingly-miniaturized electronic devices. In view of this, it's urgently needed to find an approach to improve dissipation efficiency of the water-cooling radiator without increasing its volume.

SUMMARY

An object of this application is to provide a water-cooling radiator with staggered-overlap heat-dissipation fins to overcome the shortcomings of the prior art.

Technical solutions of the present disclosure are described as follows.

This application provides a water-cooling radiator with staggered-overlap heat-dissipation fins, comprising:

-   -   a main body;     -   wherein the main body is provided with a heat-dissipation fin         assembly, a coolant tube, a water inlet and a water outlet; an         interior of the coolant tube is filled with a water coolant; the         heat-dissipation fin assembly is configured to dissipate heat of         the coolant inside the coolant tube; an end of the coolant tube         is connected with the water inlet, and the high-temperature         coolant that absorbs heat from a heat source enters the coolant         tube through the water inlet; and the other end of the coolant         tube is connected with the water outlet, and the low-temperature         coolant that flows through heat-dissipation fins flows out of         the coolant tube from the water outlet. A heat-dissipation area         of the staggered-overlap heat-dissipation fin is twice as large         as that of an ordinary heat-dissipation fin, and an angle of the         staggered-overlap heat-dissipation fin is the same as that of         the ordinary heat-dissipation fin. In addition, compared to the         ordinary heat-dissipation fin, the staggered-overlap         heat-dissipation fin only additionally takes up some space below         the fin, and the pressure increases by about one third based on         the occupied space. In the case of a 75° C. inlet water         temperature and the same flow rate, the water temperature of the         water outlet is about 2° C. lower than that of the ordinary         heat-dissipation fin, and the heat release capacity of water is         increased by 194.5 W based on H=msdT. The heat-dissipation fin         assembly is composed of two heat-dissipation fin groups         connected in an inverse overlapping manner, and the two         heat-dissipation fin groups are the same in fin spacing. The two         heat-dissipation fin groups are made by rolling, shaping,         stacking and welding.

In an embodiment, the two heat-dissipation fin groups are made of a nickel-plated aluminum alloy with symmetrical wave crest. The nickel-plated aluminum alloy has excellent heat-dissipation effects. Each of the two heat-dissipation fin groups has a waveform structure with crests made by welding has good sturdiness.

In an embodiment, a fin spacing of each of the two heat-dissipation fin groups is 3 mm which is a general fin spacing of the existing ordinary heat-dissipation fin. The staggered-overlap heat-dissipation fin assembly is composed of the two heat-dissipation fin groups with the fin spacing of 3 mm which are made by welding.

In an embodiment, the main body is provided with an upper cover and a lower cover. The upper cover and the lower cover are configured to fix interior assemblies. A first water tank and a second water tank are provided between the upper cover and the lower cover. An interior of the first water tank and an interior of the second water tank are provided with the coolant. The coolant tube is provided between the first water tank and the second water tank and an interior of the coolant tube is communicated with the interior of the first water tank and the interior of the second water tank.

In an embodiment, the coolant tube is a hollow aluminum tube because of high heat-dissipation efficiency of aluminum. The coolant tube is communicated with the first water tank and the second water tank. The coolant flows between the first water tank and the second water tank through the coolant tube.

In an embodiment, an inner side of a middle of the first water tank is provided with a blocking plate and the first water tank is connected with the water inlet and the water outlet. The blocking plate separates the water inlet and the water outlet, and the water inlet is located at one side of the blocking plate, and the water outlet is located at the other side of the blocking plate. The coolant flows into from the water inlet and flows to the second water tank through the coolant tube, then the coolant flows to the water outlet through the coolant tube in the second water tank. In this way, heat-dissipation recycle is achieved.

In an embodiment, two sides of the coolant tube are each provided with the heat-dissipation fin assembly. Heat of the coolant is dissipated by the heat-dissipation fin assembly when the coolant flows in the coolant tube. The heat-dissipation fin assembly can help the coolant quickly dissipate heat by increasing heat-dissipation area.

In an embodiment, the upper cover is provided with a water-filling plug. The coolant is added through the water-filling plug.

The benefits of this application are described as follows.

This application improves the heat-dissipation efficiency of the water-cooling radiator with the size remaining unchanged. Compared to the ordinary heat-dissipation fin, the heat-dissipation area of this application is doubled without changing the maximum size, and the wave length and height through the staggered-overlap arrangement of fins, which effectively improves the heat-dissipation efficiency of the water-cooling radiator. This application can effectively dissipate the heat generated by the electronic devices, so as to maintain the output power and operating performance of the electronic devices, and enhance the market competitiveness.

Referring to embodiments of this application shown in FIGS. 1-5 , a water-cooling radiator with staggered-overlap heat-dissipation fins includes a main body. The main body is provided with a heat-dissipation fin assembly 1, a coolant tube 2, a water inlet 8 and a water outlet 9. A first end of the coolant tube 2 is connected with the water inlet 8, and a second end of the coolant tube 2 is connected with the water outlet 9. The heat-dissipation fin assembly 1 is composed of two heat-dissipation fin groups connected in an inverse overlapping manner; and the two heat-dissipation fin groups are the same in fin spacing.

The heat-dissipation fin assembly is configured to dissipate heat of coolant inside the coolant tube 2. The high-temperature coolant that absorbs heat from a heat source enters the water inlet 8 and the low-temperature coolant that flows through the heat-dissipation fins flows out of the coolant tube from the water outlet 9 to achieve heat-dissipation recycle. A heat-dissipation area of the staggered-overlap heat-dissipation fin assembly 1 is twice as large as that of an ordinary heat-dissipation fin, and an angle of the staggered-overlap heat-dissipation fin is the same as that of the ordinary heat-dissipation fin. In addition, compared to the ordinary heat-dissipation, the staggered-overlap heat-dissipation fin only additionally takes up some space below the fin, and the pressure increases by about one third based on the occupied space. In the case of a 75° C. inlet water temperature and the same flow rate, the water temperature of the water outlet is about 2° C. lower than that of the ordinary heat-dissipation fin, and the heat release capacity of water is increased by 194.5 W based on H=msdT. The heat-dissipation fin assembly 1 is composed of the two heat-dissipation fin groups connected in an inverse overlapping manner, and the two heat-dissipation fin groups are the same in fin spacing. The two heat-dissipation fin groups are made by rolling, shaping, stacking and welding, which can well control stacked condition between fins.

In an embodiment, the heat-dissipation fin assembly 1 is composed of nickel-plated aluminum alloy with symmetrical wave crest.

The nickel-plated aluminum alloy has excellent heat-dissipation effects. And the heat-dissipation fin assembly 1 with symmetrical wave crest made by shaping, stacking and welding has good sturdiness.

In an embodiment, a fin spacing of the two heat-dissipation fin groups is 3 mm.

The specification of common fin space of 3 mm is configured to not affect existing design of water-cooling radiator. In this way, the water-cooling radiator with the two heat-dissipation fin groups with better heat-dissipation effects can be made in the same size as the existing water-cooling radiator, which can simply replace the existing water-cooling radiator.

In an embodiment, the main body is provided with an upper cover 3 and a lower cover 4. A first water tank 5 and a second water tank 6 are provided between the upper cover 3 and the lower cover 4. A coolant tube 2 is provided between the first water tank 5 and the second water tank 6.

The upper cover 3 and the lower cover 4 are configured to fix interior assemblies. An interior of the first water tank 5 and an interior of the second water tank 6 are provided with coolant. An interior of the coolant tube 2 is communicated with the interior of the first water tank 5 and the interior of the second water tank 6 to provide a necessary condition for interior recycle of the coolant.

In an embodiment, the coolant tube 2 is a hollow aluminum tube. The coolant tube 2 is communicated with the first water tube 5 and the second water tube 6.

Temperature of the coolant can be quickly decreased because of high efficiency of heat-dissipation. The coolant flows between the first water tank 5 and the second water tank 6 through the coolant tube 2. A dissipation area is increased through the thin and long coolant tube 2 so that the heat-dissipation efficiency is improved.

In an embodiment, an inner side of a middle of the first water tank 5 is provided with a blocking plate 7. The first water tank 5 is connected with a water inlet 8 and a water outlet 9. The water inlet 8 is located at one side of the blocking plate, and the water outlet 9 is located at the other side of the blocking plate 7.

The blocking plate 7 separates the water inlet 8 is located at one side of the blocking plate, and the water outlet 9 is located at the other side of the blocking plate 7. The coolant flows into from the water inlet 8 and flows to the second water tank 6 through the coolant tube 2, then the coolant flows to the water outlet 9 through the coolant tube 2 in the second water tank 6. In this way, heat-dissipation recycle is achieved.

In an embodiment, two sides of the coolant tube 2 are each provided with the heat-dissipation fin assembly 1.

Heat of the coolant is dissipated through the heat-dissipation fin assembly 1 at the two sides of the coolant tube 2 when the coolant flows in the coolant tube 2. The heat-dissipation fin assembly 1 can help the coolant quickly dissipate heat by increasing heat-dissipation area.

In an embodiment, the upper cover 3 is provided with a water-filling plug 10.

The working principle of the water-cooling radiator is as follows: the heat-dissipation fin assembly 1 is composed of the two connected in an inverse overlapping manner; and the two heat-dissipation fin groups are the same in fin spacing. In this way, a dissipation area of the heat-dissipation fin assembly 1 is twice as large as that of the ordinary heat-dissipation fin, and an angle of the heat-dissipation fin assembly 1 is the same as that of the ordinary heat-dissipation fin. In addition, compared to the ordinary heat-dissipation, the staggered-overlap heat-dissipation fin only additionally takes up some space below the fin. A dissipation surface area is doubled based on Q=hAdT, and pressure increases by about one third based on the occupied space. In the case of a 75° C.-inlet water temperature and the same flow rate, the water temperature of the water outlet is about 2° C. lower than that of the ordinary heat-dissipation fin, and the heat release capacity of water is increased by 194.5 W based on H=msdT.

In the practical application, the water-cooling radiator of the present disclosure can also be installed at the position where an ordinary water-cooling radiator is installed.

Described above are only several embodiments of the present disclosure, and are not intended to limit the disclosure.
